Re: Global vs. local?

You can replace your entire switch/case with this code:

*$SUB = sub { variableMaxText($j); };

And you're done. This will create a closure, ie a subroutine that's "closed" over $j.

This is what I initially tried - makes sense to me. In the context of this sub function, "variableMaxText" always gets called with no value getting passed. If I declare $j globally, then the last value of $j gets passed every time (e.g., if I have 5 of them, the value is always "4" no matter which GUI element makes the call).	[reply]

See Corion's reply below: if you make a copy of that variable first (with my, not local, it should work.	[reply]
